Santos, Karini Borges dos; Bento, Paulo Cesar Barauce; Payton, Carl; Rodacki, André Luiz Felix – Research Quarterly for Exercise and Sport, 2020
Purpose: The aim of this study was to determine changes in swimming parameters, stroke coordination, and symmetry after repeated high-intensity swimming efforts in swimmers of different performance levels and para-swimmers. Method: Forty swimmers (20 able-bodied, allocated to higher and lower performance groups--G1 and G2, respectively--and 20…

Southard, Dan L. – Research Quarterly for Exercise and Sport, 2014
Purpose: The purposes of this study were to: (a) examine the effect of experience and goal constraints (speed, accuracy) on kicking patterns; (b) determine if effective striking mass was independent of ankle velocity at impact; and (c) determine the accuracy of kicks relative to independent factors. Method: Twenty participants were recruited to…

Floría, Pablo; Harrison, Andrew J. – Research Quarterly for Exercise and Sport, 2013
Purpose: The aim of this study was to ascertain the biomechanical differences between better and poorer performers of the vertical jump in a homogeneous group of children. Method: Twenty-four girls were divided into low-scoring (LOW; M [subscript age] = 6.3 ± 0.8 years) and high-scoring (HIGH; M [subscript age] = 6.6 ± 0.8 years) groups based on…

Stodden, David F.; Langendorfer, Stephen J.; Fleisig, Glenn S.; Andrews, James R. – Research Quarterly for Exercise and Sport, 2006
The purposes of this study were to: (a) examine differences within specific kinematic variables and ball velocity associated with developmental component levels of step and trunk action (Roberton & Halverson, 1984), and (b) if the differences in kinematic variables were significantly associated with the differences in component levels, determine…

Stodden, David F.; Langendorfer, Stephen J.; Fleisig, Glenn S.; Andrews, James R. – Research Quarterly for Exercise and Sport, 2006
The purposes of this study were to: (a) examine the differences within 11 specific kinematic variables and an outcome measure (ball velocity) associated with component developmental levels of humerus and forearm action (Roberton & Halverson, 1984), and (b) if the differences in kinematic variables were significantly associated with the differences…

Southard, Dan – Research Quarterly for Exercise and Sport, 2006
The purpose of this study was to determine the effects of instruction and scaling up a control parameter (velocity of throw) on changes in throwing pattern. Sixty adult female throwers (ages 20-26 years) were randomly placed into one of four practice conditions: (a) scale up on velocity with no instruction, (b) maintain constant velocity with no…
